This technology has been tested in randomized controlled trials using the endpoint of improvement in RV/left ventricular (LV) ratio because this predicts mortality . Bedside transthoracic echocardiography documented moderately severe RV hypokinesis, moderate tricuspid regurgitation, and an estimated pulmonary artery systolic pressure of 55 mm Hg. These .
Right ventricular dysfunction (RVD) is associated with adverse outcomes of acute pulmonary embolism (PE). However, there are no studies describing the long . Massive pulmonary embolus (PE) is defined as PE with sustained hypotension (systolic BP < 90 for at least 15 min), need for inotropic support, or .
A substantial reduction in RV/LV ratio was achieved (from 1.56 to 1.15 over 48 hours, on average). Nearly all patients received no thrombolytic, so this was a true study of mechanical intervention. Low-risk acute PE has no evidence of hemodynamic compromise and no evidence of RV strain, defined as a right to left ventricular diameter ratio (RV/LV) > 0.9 . The 2019 National Confidential Enquiry into Patient Outcome and Death for PE demonstrates that this metric is poorly reported. We assess the feasibility of an entirely automated RV:LV analysis and .
This study designs and validates a completely automated Computer Aided Detection (CAD) system to compute the axial RV/LV diameter ratio from CTPA images .

Introduction The right ventricle to left ventricle (RV:LV) ratio >1 on CT pulmonary angiography (CTPA) is the most important predictor of adverse outcomes in acute pulmonary embolism (PE). The .
Background. Right ventricular (RV) dysfunction caused by acute pulmonary embolism (PE) is associated with poor short- and long-term prognosis. RV dilatation as a proxy for RV dysfunction can be assessed by calculating the right-to-left ventricle diameter (RV/LV) ratio on standard computed tomography pulmonary angiography (CTPA) images. Also note larger RV than LV (RV/LV ratio, 1.20), flattening of interventricular septum (arrowhead) and thickened RV free wall (thin arrows, measuring up . the patient showed RV dysfunction with RV/LV ratio greater than 1.0 when diagnosed with acute PE. (B) CT scans obtained in March 2012 demonstrate that all emboli have resolved .No significant relationship was found between RV/LV ≥1 and mortality (p= 0.908). All patients with PTE-related mortality had RV/LV ratio ≥1 in CTPA and had IVC reflux. Patients with an RV/LV ratio of ≥1 had statistically significantly higher troponin levels (p= 0.004) and IVC reflux (p= 0.025) compared to patients with an RV/LV ratio of <1.Download scientific diagram | Measurement of RV/LV ratio. Axial CT images demonstrate the best approximated four-chamber view. Calipers are placed from inner wall to inner wall at the maximal .RV/LV EDD ratio > 0.7 has good accuracy for the diagnosis of acute PE. RV/LV area ratio > 0.7 and McConnell sign are specific but not sensitive indicators of acute pulmonary embolism. The presence of these findings should prompt further diagnostic testing for PE.
Higher RV/LV ratios increase specificity for decompensation (16–18) regardless of the patient’s hemodynamic stability. Therefore, RV/LV ratios of >1.0 should be used to risk stratify patients . This is as recommended in current clinical practice guidelines, as outlined in the 2019 European Society of Cardiology recommendations .
Although increased RV/LV ratio is an independent predictor of 30-day mortality in acute PE, the impact of change in RV/LV ratio at 24-48 hours on long-term mortality and morbidity in intermediate-risk PE remains unresolved. As such, the optimal treatment for most patients with intermediate-risk PE in 2018 is still unknown.Patients with intermediate- and high-risk PE represent the populations at highest risk for early mortality. • Although immediate anticoagulation is the cornerstone of management, patients with intermediate- to high-risk PE who deteriorate despite anticoagulant therapy and those with high-risk PE should be considered for advanced therapies.
Aim: Increased ratio between the right and left ventricular (RV/LV) diameters ≥1 is considered an important imaging marker for risk stratification among patients diagnosed with acute pulmonary embolism (PE). Our goal was to assess the prevalence of RV/LV≥1 among consecutive patients undergoing computed tomography pulmonary . This trial enrolled 119 patients with intermediate-risk acute PE and showed a significant reduction of mean RV/LV ratio at 48 h. The median ICU length of stay was 1 day and 1.7% of the patients experienced major adverse events at 48 h including one device-related death [ 24 ].A right ventricle/left ventricle (RV/LV) ratio >1.0 was not associated with fewer favorable outcomes in patients with symptomatic acute pulmonary embolism (PE) who were otherwise considered low risk, , according to study results published in The American Journal of Respiratory and Critical Care Medicine.. In this patient-level post-hoc analysis of 2 Dutch .
The RV/LV ratio measured on transverse sections is the most predictive parameter [16,17,18,19]. In a cohort of 411 patients with hemodynamically stable PE, an RV/LV ratio ≥ 0.9 was associated with increased death or clinical deterioration (HR 3.8, 95% CI 1.3–10.9, p = 0.007) .
There are many studies on the association between RV/LV ratio and PE outcomes. RV/LV ratio greater than 0.9 in the short axis was proposed as a sign of poor outcome and a higher 30-day risk of mortality [17,18,19]. However, there are some other studies reporting higher cutoff points including 1, 1.2, and 1.5 for the RV/LV ratio to be .rv lv ratio pe Management of Submassive Pulmonary Embolism In the A4 view, the RV:LV ratio should be approximately 0.6:1. An RV:LV ratio >1:1 indicates RV dilation and should raise suspicion for elevated pulmonary pressures (Figure 2). Additionally, evaluating for septal flattening, or the ‘D’ sign, can be identified in the parasternal short axis (PSS) mid-papillary view (Figure 3). In 2020, the Radiological Society of North America and Society of Thoracic Radiology sponsored a machine learning competition to detect and classify pulmonary embolism (PE). This challenge was one of the largest of its kind, with more than 9000 CT pulmonary angiography examinations comprising almost 1.8 million expertly annotated .
The primary aim of this study was to assess the incidence of CT-measured RV dilatation, defined as a CT-assessed RV/LV diameter ratio greater than 1.0 with the ventricular diameters measured in the transverse plane at the widest points between the inner surface of the free wall and the surface of the interventricular septum, and its impact on clinical .
